Hi,

We are configuring a 2 node oracle 11g rac and a failover clustering on the same nodes.

The configuration is as follow.
Node1
Public Nic : 1.1.1.1
Private Nic : 10.0.0.1
Public Virtual IP for Oracle : 1.1.1.2

Node2
Public Nic : 1.1.1.3
Private Nic : 10.0.0.2
Public Virtual IP for Oracle : 1.1.1.4

The installation was first we configured oracle 11g rac and verified the rac is working fine. After configuring Failover clustering on the same nodes, the oracle vip does not come online. but if i disable Microsoft failover virtual adapter, the oracle vip's comes online.

Note : the Oracle vip's are entered only in the hosts file and not configured to any of the nic.

My question is that can Oracle 11g rac and microsoft failover clustering co-exist or do we have to dedicate separate nic's for microsoft cluster and oracle rac.

Need suggestions.

thanks in advance..
